Abstract
A power tool includes a housing, an output member that rotates about a longitudinal axis, and a motor drivably connected to the output member. A rotational motion sensor is arranged in the housing and operable to detect a user input that includes a rotational motion of the housing in a desired rotational direction about the longitudinal axis of the output member. A controller is configured to receive a first input indicative of a user-desired rotational motion of the output member, and a second input, from the rotational motion sensor, indicative of an actual rotational motion of the power tool. The controller determines a user-desired rotational direction of the output member about the axis from the first input, determines an actual rotational direction of the housing about the axis from the second input, and causes the motor to drive the output member to simulate ratcheting movement in the user-desired rotational direction.
